2. ¤ Its based on Vacuum supply(Negative pressure) and Pulsation. ¤ Vacuum supply(Negative pressure) = 11-14 inches of Hg ¤ Pulsation rate= 50-60 cycle per minute ¤ Negative pressure and Pulsation helps to remove and move down milk from udder. ¤ Negative pressure open the teat canal through partial vacuum. ¤ Pulsation also help in massages the teat. ¤ Principle of Milking Machine

3. ¤ Hand operated Milking Machine Mechanically operated by handle Avilable in cheaper cost Generally use in small dairy farm or house hold use ¤ Electric Motor Operated Milking Machine Electrically Operated by motor Generally use in small dairy farm ¤ Types of Milking Machine

4. Applying of Machine And Precaution ¤ Regularity of time and routine required. ¤ Before starting milking properly wash udder and teats with clean water. ¤ Massage the cow’s udder and Dry udder and teats. ¤ Use strip cup to remove few streams of milk. ¤ Applying teat cups and checking teat cup placement proper or not. . .

5. Machine-on time : ¤ Maximal intra mammary pressure caused by milk letdown occurs at about one minute after udder preparation begins and continues for about 5 minutes. ¤ Most cows will milk out in 5 to 7 minutes Detaching the machine at the end of milking ¤ The vacuum must be turned off before the machine is removed. ¤ Otherwise, pulling on the teat cups while the vacuum is still on may cause trauma to the teat ends. ¤ Shut off vacuum and remove unit when milk flow. NOTE:- ¤ Washing the machine between every milking. ¤ Treated and sick cows shall always be milked separately and after all the healthy cows.

6. Benefits of the Machine Milking ¤ First of all, it allows the dairy farm to increase their activity with a larger herd . ¤ In machine milking the peak yield is achieved quicker and remain longer so total yield is more. ¤ Its avoid contamination of outside –bacteria and foreign material.

7. ¤ Minimum irritation to the udder, teats and tissues. ¤ Its easy to operate ,save time and labour expenses . ¤ Prevent invasion of external organisms . ¤ Proper milking machinery can manage herds faster while ensuring the quality of the milk. ¤ Milking machinery also reduces the farm’s dependency on workers. Benefits of the Machine Milking

8. Disadvantages of Milking Machinery ¤ The most obvious disadvantage will come with older cattle. That's normally used to hand milking. ¤ Older cows will have trouble adjusting to automatic milking machinery. ¤ This may increase their stress levels and reduce their milk quantity and quality.

9. ¤ Secondly, the machinery will need a constant supply of electricity. ¤ This means that in cases of damages to the power supply system the dairy farm will not be able to operate properly. ¤ Its also require emergency power supply systems. ¤ Milking machinery require strict cleaning procedures. ¤ Because of improperly cleaned machinery can lead to infections.
